The images showed that during intercourse, whatever the position,the penis is never straight, as drawn by Leonardo da Vinci and Zwang, but takes on the shape of a boomerang and not of an S, as described by Dickinson.These three authors clearly underestimated the size of the root of the penis.The boomerang shape of the erect penis could be the explanation for theanatomical differences between the theoretical diagrams and those obtainedby our MRI study.
